ISEA 12 Poster Session P1 for sessions S3 and S4

Monday, May 19, 2008 (evening)

Conveners: G. Swenson (S3) and D. Pancheva (S4)
Poster chairs : G. Lehmacher and D. Riggin

S3: Equatorial lower and middle atmosphere

This session will deal with (a) instrumental techniques, (b) structure, (c) dynamics and (d) new developments. Three invited talks shall be on items (a), (b) and (c). Contributed papers are solicited to be submitted on all four items, where item (d) would be particularly welcome. Papers should on the whole cover: (a) MST, IS, meteor and MF radars, as well as lidar and passive optical systems in the equatorial region, balloon and radiosondes, RASS technique and satellite remote sensing. (b) Irregularities, such as neutral turbulence, interaction with lower ionosphere plasma, temperature structure and chemical composition. Layering phenomena in the middle as well as in the lower equatorial atmosphere. (c) Troposphere-stratosphere-mesosphere coupling (convection, gravity waves etc.), equatorial waves and tides, QBO/ENSO, longitudinal variability, modeling and observations. (d) Any new ideas and recent as well as planned development of decent observing methods, networking, simulations and modeling are particularly welcome.

Keywords: structure and dynamics of the equatorial troposphere, stratosphere, and mesosphere, instruments, observations, simulations and modeling.

S4: Equatorial and mid-latitude MLT dynamics

The session invites observational and modeling studies that address the dynamics of the equatorial and mid-latitude MLT region with particular emphasis on chemistry and transport, heat sources and sinks, solar and lower atmospheric forcing and the associated feedback on dynamics. Contributions are sought that focus on atmospheric waves (gravity, planetary, and Kelvin waves, tides), wave-mean flow interactions, chemical and dynamical coupling processes and the MLT response to equatorial oscillations such as QBO and SAO. New results on MLT wave seeding (wave penetration and secondary wave generation) of ionospheric disturbances are most welcome.

Keywords
  • Observational and modeling studies of MLT dynamics, chemistry and energetics
  • Atmospheric waves, breaking and dissipation in the MLT region, including wave-mean flow coupling
  • Solar and lower atmospheric forcing processes
  • Equatorial MLT phenomena: QBO, SAO, etc.
  • MLT wave seeding of ionospheric disturbances
